1. e4 Nc6 2. Nf3 is unusual but not crazy.
2. ... d4 seems suitably aggressive; the black queen backs her pawn up, the white king can't.
3. Bd3? Gates is trying to protect his pawn (and preparing to castle), but ends up blocking in his black bishop; better is 3. d3.
3. ... Nf6
4. exd5? Qxd5 lets the black queen out of her hidey-hole.
5. Nc3 Qh5 White tries to play queen-be-gone, but the queen is happy to be on her way.
6. 0-0? Dude, with the queen sitting on h5? 6. ... Bg4 after the knight on f3.
7. h3 trying bishop-be-gone; perhaps White should have played this instead of castling. 7. ... Ne5 again contending for f3.
8. hxg4 Nfxg4 aiming for h2 while keeping an attack on f3.
The only thing that saves White at this point is 9. Re1 giving the king an escape route and developing the rook. Anything else and, at best, 9. ... Nxf3+ 10. Qxf3 or gxf3 Qh2#. But White played about the worst move he could have made:
9. Nxe5?? Qh2#.
